Detailed Description

allocate/free texture units.

vtkTextureUnitManager is a central place used by shaders to reserve a texture unit ( Allocate() ) or release it ( Free() ).

Don't create a vtkTextureUnitManager, query it from the vtkOpenGLRenderWindow

static int vtkTextureUnitManager::IsTypeOf ( const char * type )

static

virtual int vtkTextureUnitManager::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

protectedvirtual

vtkTextureUnitManager* vtkTextureUnitManager::NewInstance ( ) const

void vtkTextureUnitManager::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static vtkTextureUnitManager* vtkTextureUnitManager::New ( )

static

void vtkTextureUnitManager::SetContext ( vtkOpenGLRenderWindow * context )

Get/Set the context.

This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions.

virtual vtkOpenGLRenderWindow* vtkTextureUnitManager::GetContext ( )

virtual

Get/Set the context.

This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions.

int vtkTextureUnitManager::GetNumberOfTextureUnits ( )

Number of texture units supported by the OpenGL context.

virtual int vtkTextureUnitManager::Allocate ( )

virtual

Reserve a texture unit.

It returns its number. It returns -1 if the allocation failed (because there is no more texture unit left).

Postcondition: valid_result: result==-1 || result>=0 && result<this->GetNumberOfTextureUnits()); allocated: result==-1 || this->IsAllocated(result)

bool vtkTextureUnitManager::IsAllocated ( int textureUnitId )

Tell if texture unit `textureUnitId' is already allocated.

Precondition: valid_textureUnitId_range : textureUnitId>=0 && textureUnitId<this->GetNumberOfTextureUnits()

virtual void vtkTextureUnitManager::Free ( int textureUnitId )

virtual

Release a texture unit.

Precondition: valid_textureUnitId: textureUnitId>=0 && textureUnitId<this->GetNumberOfTextureUnits(); allocated_textureUnitId: this->IsAllocated(textureUnitId)

void vtkTextureUnitManager::DeleteTable ( )

protected

Delete the allocation table and check if it is not called before all the texture units have been released.

static int vtkTextureUnitManager::IsTypeOf ( const char * type )

static

virtual int vtkTextureUnitManager::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Get/Set the context.

This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions.

virtual vtkOpenGLRenderWindow* vtkTextureUnitManager::GetContext ( )

virtual

Get/Set the context.

This does not increase the reference count of the context to avoid reference loops. SetContext() may raise an error is the OpenGL context does not support the required OpenGL extensions.

int vtkTextureUnitManager::GetNumberOfTextureUnits ( )

Number of texture units supported by the OpenGL context.

virtual int vtkTextureUnitManager::Allocate ( )

virtual

Reserve a texture unit.

It returns its number. It returns -1 if the allocation failed (because there are no more texture units left).

Postcondition: valid_result: result==-1 || result>=0 && result<this->GetNumberOfTextureUnits()); allocated: result==-1 || this->IsAllocated(result)

virtual int vtkTextureUnitManager::Allocate ( int unit )

virtual

Reserve a specific texture unit if not already in use.

This method should only be used when interacting with 3rd party code that is allocating and using textures. It allows someone to reserve a texture unit for that code and later release it. VTK will not use that texture unit until it is released. It returns -1 if the allocation failed (because there are no more texture units left).

Postcondition: valid_result: result==-1 || result>=0 && result<this->GetNumberOfTextureUnits()); allocated: result==-1 || this->IsAllocated(result)

bool vtkTextureUnitManager::IsAllocated ( int textureUnitId )

Tell if texture unit `textureUnitId' is already allocated.

Precondition: valid_textureUnitId_range : textureUnitId>=0 && textureUnitId<this->GetNumberOfTextureUnits()

virtual void vtkTextureUnitManager::Free ( int textureUnitId )

virtual

Release a texture unit.

Precondition: valid_textureUnitId: textureUnitId>=0 && textureUnitId<this->GetNumberOfTextureUnits(); allocated_textureUnitId: this->IsAllocated(textureUnitId)

void vtkTextureUnitManager::DeleteTable ( )

protected

Delete the allocation table and check if it is not called before all the texture units have been released.
